PostgreSQL is a fully featured object-relational database with many enterprise features: ACID transactions, inheritance, unicode and strong support for the SQL-92 standard including subqueries, views, outer joins, foreign keys, sequences and triggers. PostgreSQL is a important database, but WordPress can’t support it now. I hope WordPress will support PostgreSQL. Not only PostgreSQL,but also others databases are not support directly. You must write configs or install plugins then WordPress will works. Turns out that Wordpress doesn’t support postgresql. There is a plugin that “claims” to resolve the issue - But I don’t like using plugins in general. They slow down the site.

Installing Metasploit Framework + PostgreSQL Under VMware BackTrack 5
  1. Wordpress + Postgresql. Ask Question Asked 6 years, 2 months ago. Active 6 years, 2 months ago. Viewed 2k times 0. I’ve painted myself into a corner. I hired someone to build a database with all kinds of cool search features and such. The programmer wasn't aware that my site is built on Wordpress.
  2. Wordpress+with+postgresql What the heck is wordpress and what is it for? If you had asked that question a few years ago, most people probably would have unk.

I’ve just installed the new and improved BackTrack 5 in VMware. As always, i made an apt-get update && apt-get dist-upgrade -y and after that a msfupdate.I launched Metasploit framework, and was about to start postgresql when i realized that BT 5 is with MySQL.

I created a workaround script, its not pretty but it works. You will need the following packages installed before running the script:

apt-get install postgresql-client libpq-dev

Copy the script into a file e.g script.sh,

chmod +x script.sh, ./script.sh

The commands (script.sh ) I used was:

This is an old, deprecated version of the Ruby PostgreSQL driver that hasn’t
been maintained or supported since early 2008.

You should install/require ‚pg’ instead.

If you need the ‚postgres’ gem for legacy code that can’t be converted, you can
still install it using an explicit version, like so:

gem install postgres -v ‚0.7.9.2008.01.28’
gem uninstall postgres -v ‚>0.7.9.2008.01.28’

WordPress requires that you use a MySQL compatible database for its database backend. It used to be that you could confidently choose MySQL and go on with life, but in 2019 the choice isn’t quite that simple. With the MySQL, MariaDB, and Percona as the attractive options, how do you know which to choose?

Choosing a database isn’t always about performance, but for the sake of this article it will be 🙂

For this series of tests we tested database performance out-of-the-box with no special tweaks. It is quite possible that a professional database administrator could make each database run more performant, but most people hosting WordPress aren’t DBAs. With regards to caching, none was enabled. We wanted to test database performance, not cache performance.

What was tested?

The WordPress host machine was a DigitalOcean CPU Optimized droplet with 16 vCPUs (dedicated hyper-threads) and 32 GB of RAM. This monster of a machine was chosen so that we could be certain that Nginx + PHP-FPM weren’t the cause of any bottlenecks. A minor tweak to the PHP-FPM config allowed for full use of all 16 vCPUs.

The database host machines were DigitalOcean CPU Optimized droplets with 4 vCPUs (dedicated hyper-threads) and 8GB of RAM. CPU Optimized droplets were chosen because we didn’t want our tests to be at the mercy of shared CPU resources.

Each deployment was in DigitalOcean’s SFO2 region with the WordPress server communicating with the database over the internal private network. The traffic producing nodes were deployed in DigitalOcean’s NYC3 data center and communicated via the public internet.

The software versions are as follows:

  • Percona Server for MySQL 8.0.16-7
  • MariaDB 10.4.8-GA
  • MySQL 8.0.18

What tests were run?

For each database that was tested, we ran a load test with the following parameters:

  • 500 concurrent users
  • 2 req/s ramp up
  • 30 minute duration

The goal here wasn’t to bring the database to it’s knees but instead see how it performed under sustained heavy load, but not so heavy that it falls over.

MariaDB WordPress Performance

During the MySQL acquisition of Oracle in 2009 there was a lot of concern amongst the core developers that Oracle would eventually close off MySQL to the world (similar to Oracle’s business model). Before that could take place, a GPL fork of MySQL was created named MariaDB.

MariaDB is open source and in active development. But how does it stand up to our WordPress load tests? Let’s find out.

First we’ll take a look at the requests and failures per second.

As you can see from the results above the performance scales up very well over time eventually peaking at ~379 req/s. We see periodic database-related errors (the vCPUs on the database were almost completely saturated) but nothing too crazy. Next, let’s see how the response times look.

Wordpress Postgresql Docker

The median response time of WordPress when backed by MariaDB under heavy load stays remarkably consistent. You can see that the average is slowly creeping up by the end of the test, but nothing that would be noticeable by customers yet.

The response time distribution is a little more interesting than the median response time. 90% of all requests finish in under 300ms and 99% of all requests finish in less than 500ms. Overall, the performance of MariaDB out of the box with no configuration is quite good.

Windows

Percona WordPress Performance

Another open-source fork of MySQL, Percona was started in 2006 and has been steadily delivering value-added features and enterprise support on top of MySQL for more than 12 years. With all that accumulated experience, how does Percona measure up?

Overall the Percona WordPress performance was pretty good. Not quite a good as MariaDB but nothing to scoff at. The one interesting thing was that the error rate was consistent across most of the test once the request volume passed ~200 requests/s. Lets see if the response time graph adds to the story.

The data here is actually pretty interesting. The response time for Percona was comparable to MariaDB right up until the time it started getting consistent errors. After that, it more than doubled and stayed that way for the rest of the test.

The response time distribution tells similar story to the response time chart. The difference between the 50th percentile and the 99th percentile shows that performance was very consistent across the entire test, it just wasn’t as good as MariaDB.

MySQL WordPress Performance

Last but not least (well….) in our test is MySQL. It’s been around since 1994 and is now owned by Oracle. In it’s latest releases there has been lot of great features such as window functions and more JSON features to compete with PostgreSQL. So let’s see how it did.

Wordpress Postgresql

MySQL had a similar trajectory to Percona: It did pretty good across the board with a small but consistent series of errors after it started to go past 200 req/s. Also note that it never achieved higher than 300 req/s, which both MariaDB and Percona did.

Postgresql With Wordpress

The shape of the MySQL response time graph looks nearly identical to Percona, just about 50ms slower once the vCPUs started to get saturated. The detailed look in the response time distribution tells a similar story.

The response time distribution is where you can see Percona and MySQL diverge a bit. At the 99th percentile MySQL is returning at 875ms, while Percona was more like 550ms. In general, the distribution matches what one would expect given how the response time graph looks

Conclusions

Wordpress Postgresql Windows

The out of the box numbers for MariaDB make it look like the clear winner here. And compared to both Percona and MySQL it is in the raw performance department. This isn’t to say that you couldn’t tune Percona or MySQL to out-perform MariaDB, but only that you get more performance with zero configuration changes.
